To all whom it may concern;

Be ilknow'n O. Amavva:

tham, in the county of Middlesex'and State of Massachusetts, have invented certain new, and useful Improvements inJewel-Pin and Pallet-Stone Setters, of which the following is aspecification. i v t The object of this inventionis toprovide a tool by which jewel-pins may beset and ad justed inthe roller-tables otbalance-wheels' without injury to the balances or hair springs by reason of'the heat used'tosoften thjesheh lac bywhichthe jewel-pins are secured, and also to provide the same toolwitlifineansjby' which a pallet of a watch-escape nentmay be firmly. held while the stones thereof are set and adjusted. In setting and adjusting pallet-stones and jewel-pins shellac is used for securing the jewels in place, and itis necessary that the shellac should be softened by heatinorder to permit of adjustment. It is customary to apply the heatby means ofa flfiIIlG from an alcohol-lamp, and hitherte' with the meth ods in use it has beenextremely diff cult to apply the heat of the flame sufficiently to soften the shellac without burning the hairspring and parts of the balance-wheel or distorting or otherwise injuring the pallet or chippingand cracldngthe jewels, and in con sequence many of these parts ofwatch'or' clock movements have been spoiled.

By the presentinventionl have produced an improved tool capable of holding a pallet in such position that its jewels maybe readily set and adjusted and having alsomeans for holding a jewel-pin and a balancewheel in position whereby they may be properly assembled and providedwith a heat-conduct in? shield "capable of permitting enough heat to be applied to the roller-table of thebalance orthe pallet to soften the shellac without per Initting direct contact with the flame, thus preventing excessive heating andinju'ry' of any of the parts.

Of the accompanying drawings, Figure 1 represents a perspective view of the device embodying my invention. Fig. 2 represents a plan view of the same. Fig. 3-representsa longitudinal vertical section on lineS 3 of'Fig'. 2 on an enlarged scale. crosssection of the tool on lined 4 0'1 2. Figs. 5 and 6' representtwo plan views of the tool, showing the pallet-holding de'vicein operative position, illustrating the manner of holding two pallets of difi'erentkinds. Fig. 7

,i 1 representsthe shank forming a part of the ibojjdy portion of the improved tool constitutitached aha ndle 2 and the forward part of orifice in which is secured ascrew projection 4, the upper end of which is flush with the up 5 extending'downwar'd from its upperend and directed longitudinally of the tool. Upon the approximately equal distances in alldirec} ;t1ons'irom the center of the screw.

Plates -7 8 are secured to the shank 1 ofthe tool, and pivoted between them at Q'is a gripgnall of the tool and has its forward end adj acent the slot 5 ofthe screw, this end having also a slot 11, which is parallel to the slot 5,

upon the plate on both sides of the'slot' 15, being'impelled'itliereto by a spring 12; By sepa finger plate 13, secured to the gripper, a :balaiice-wheelmay be placed between the with one end of its stafl 14 extending into the sloth and its other; end projecting through slot 11. In placing a balance between the lgrippers for setting a j e'wel-pin the roller itable 15-is placed so as to rest upon the plate 1&3, whichconstitutes the relatively stationary jj aw ofthe g'1'i pi11g "airwith its side having the hole 16, in which the j ewcl-pin is set, projSlots h and 11 are longenough and so located ;asto permit a balance-wheel of any size ordi narily used to beheld by thetool in proper position for the attachment Of a j ewel-pin.

Atthe forward end 'ofthe plate and in line 17 inwh'ich a'jewel-pin 18 may be placed-and wherein it is held by the jaw 20 of a gripper body portion bf the tool and held by a spring ing my mvention, to the end of whichis at-,

1' which supports a plate 3, having considerable. lateral extent anda fiat upper surface. Ne/er" lits forward end thisplate is provided. wlth an per surface of the plate and which has aslot downwardly-projecting portion of the screw ;is threaded so as to be detachable and also.

extend beyond the sides and end of plate 3 per or clamp 10, which extends longitudi and forming a fork which is adaptedto bear aratingthe iorward end of lever 10 from plate 3 by pressure of the thumb of the operator on jplate and gripper, as shown in Figs. 2 and 3,

jecting over the forward end of the plate 321, pivoted to a-wing 22," extending from the outward and i's't'hen engaged by the flat surface of the jaw 20, which is perpendicular to the slot 5 when in position to engage the jewel-pin. The jaw then in pressingupon thefiat surface of the pin automatically adjusts it so that it will face exactly away from the center of a balance, which is subsequently placed between the plate 3 and gripper 10, and thus when the balance is so placed and moved toward the end of the tool until the hole 16 in the roller-table is over the jewel-pin and is then moved toward the plate.

the jewel-pin is accurately positioned in the roller-table with its flat face exactly tangential to the path of movement in which it is designed to travel.

The shellac, which is placed upon the rollertable and in the hole 16, is softened by passing the tool over the flame of an alcohol-lamp before the jewel-pin is placed in the roller-table and is afterward softened to permit whatever Y adjustment of the pin may be necessary, and

when being passed through the flame one of the functions of the plate 6 is utilized. This plate then acts as abaffie, deflecting the flame of the lamp from contact with the hairspring or any part of the balance-wheel or the jewel-pin, but at the same time conducting enough heat to the parts to cause the required softening of the shellac. Another function which the plate 6 can perform is that of an adjusting device for placing the jewel-pin in proper longitudinal position in the roller-table. When the j ewel-pin is held in the notch 17, one end rests against plate 6, and by unscrewing or screwing up the plate to vary its distance from the. plate 3 the amount by which the jewel-pin projects above the surface of said plate 3 on which the roller-table rests may be varied, and consequently the jewel-pin may be accurately adjusted to project by the proper amount from the rollertable. The plate 3 also is shaped to constitute a guideway, as it is formed with undercut sloping sides 25, which are engaged by overlapping tabs 26 of a slide 27, which is supported upon the upper surface of the plate 3 and is movable on the same toward and away from the forward end thereof, its forward movement being limited by a stop 28 on the end of the plate which is engagedby the slide. This slide has sockets 29, adapted to receive the stafiof a pallet resting upon the slide and in line with the sockets.

Extending longitudinally of. the slide is a slot 30, into which the guard-pin of the pallet-fork may extend. In this slot is mounted a clamp 31, made of a piece of spring metal bent double and movable in the slot, being held in any adjusted position by the frictional contact due to its resiliency with the sides of the slot. The clamp also has flanges 32, projecting laterally into channels on the inner surface of the slide beside the slot. When a pallet is placed upon the slide with its staff extending into one of the sockets 29 and its forked arm extending rearwardly, the clamp 31 is moved up into the fork to hold the same against lateral displacement, and the pallet is further held by the gripping-clamp 10, which rests upon it, the slide being moved to the end of the tool for this purpose. The slide also has slots 33 in its opposite sides in line with each other and also with one of the sockets 29, these slots being perpendicular to the slot 3 1 and adapted to receive the guard-pin of a pallet having the form of that shown in Fig. 6, in which the fork is in line with the jewel-bearing arms of the pallet instead of being on an arm perpendicular thereto. It will be seen that the arrangement of sockets and slots permits pallets of all kinds to be used, while those of all sizes may also be accommodated. When the slide is moved forward, a pallet may be grasped between it and the clamping-arm 10, the balance-receiving slot 5 being then covered up, and when the j ewel-pin is to be set in a balance the slide is moved rearward to un cover the plate 3 and permit the balance to be a plied. The plate 6 serves, in connection with both holding means, to deflect the flame of the lamp. 7

Slide 27 has a handle 35, by which it may be moved, and beneath the handle is a piece 36, secured to the slide by a screw 37 which piece has a beveled side to fit one of the beveled sides 25 of the body portion and may be clamped against the same like a gib to take up wear and also to vary the amount of friction between the slide and its guide.
